DISH-W'ASHIN DEVICE.

Specification of Letters Patent.

Application filed March 19, 1910. Serial No. 550,437.

and State of California, have invented new and useful Improvements in Dish Washing Devices, of which the following is a specification.

This

containing baskets are suspended in balanced relation in a washing and a rinsing tank, respectively in such manner that the operator can work the baskets alternately up and down in the tanks so as to simultaneously wash and rinse the dishes in the separate baskets.

The invention has for one of its objects to improve and simplify the construction and operation of machines of this character so as to be comparatively simple and inexpensive to manufacture and keep in operative condition, so as to be reliable and etlicient in use, and of such design that the various operations can be carried on with great case and despatch.

Another object of the invention is the provision of a balance lever adapted to suspend at o posite ends of the dish containing baskets, tl io lever being mounted on a traveling carriage jmovable on an overhead rail above'the combined tank sink and drier and on which carriage the lever is n iovable vcrtically to dillerent positions so that the baskets can be lowered in or raised out of the tanks and transferred from one tank to the other and from the rinsing tank to the i and cllicient manner.

With these objects in view andothers as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the ,accompanying drawings, which illustrate one embodiu'ient of the invention; Figure, 1 is a perspective View of the apparatus. Fig, 2 is a vcrtical'longitutlinal section thereof". Fig. 3 is a. vertical transverse section of the apparatus. Fig. 4 is a front view of the basketsuspending and invention relates to a dish Washing, machine of that type in which two dishcarrying device, showing the lever ing only one basket. H

Similar reference characters are employed to designate cmrespouding out the several views.

Referring to the drawings, A designates a sink of any improved constructionwhich has at one end a receiving table 1, and at the suspend- .atented Apr.'18,

parts through-- opposite end a discharge table 2, and under the sink are Washing and rinsing tanks 3 and l, disposed side by side, each tank being open at the-top and preferably forming'a part of the sink so that overflow water from the tanks will be collected in the sink from which it can drain through the drain-pipe 5. The discharge table 2 is provided with a drier B, so that a basket of rinsed dishes can be set over the opening 6 of the'table' 2 and dried by the heated air which ascends from the drier. This drier B consistsof upper and lower drums 7 and 8, thc upper drum being slightly larger than the lower and into which the latter extends. ported over the upper end of the'lower drum or cylinder is a hood 9, which serves as. a deflector for the heated aii' and as a shed for preventing the dripping water from the dishes from dropping on the burner 10.

The water in the tanks 3 and L is kept hot hy heaters ll and 12, and each tank hasa hot water supply pipe 13 and a drain "pipe l4. \Vithin each tank may be arranged a stool-like support 1 5 on which the dish-coa laining basket can rest in the tank.

Supported over the sink A is an overhead rail 16, on which is mounted a traveling car riugc C, the same being in the form of a rectangular frame provided with hangers 17 on its upper ends, which hangers have rollers 18. that ride on the rail. This carriage C supports a basket suspending device which, in the present instance, is in the form of a balance lever 19, which has its extremities disposed in vertical guide ways 20 in the side members 21 of the carriage frames This lever is l'ulcrunied at 22, on a vertically dis posed; rod 2 1, that slidesvertically in a guide 24, at the top of the carriage frame. 'lhe lever and rod 523 are supported by a flexible element or cable 25, which passes over apullcy 26 at the top ofthe carriage frame and connects at 27 with the lower end of the rod 23, the flexible element being adapted to wind around a drum 27 on av horizontal shaft 28, journaled on the carriage frame at the bottom thereof. The shaft 28 has an operating crank 29, whereby the drum 27 can be turned. To prevent the drum from turning in one direction, a ratchet wheel 30 is secured thereto and with which cooperates a pawl '31, mounted on the carriage frame. The ends of the lever have depending chains 32, that carry hooks 38 to engage the bails 34 of the dish containing baskets 35. The balance lever 19 is prevented from having too great a play laterally by stops 36 arranged to, engage the side members 21 on the carriage frame. On the members 21 are rollers 37, which serve-as stops for limiting the upward movement of the lever and on these rollers, the lever will have a limited longitudinal movement whenever the lever ascends while in a tilted position, when the dishes in one basket are heavier than those in the other basket, until the lever is horizontal. In order to assist in maintaining the lever approximately horizontal and to render the oscillation of the lever easier, springs 38 are connected with the lever at opposite sides of the fulcrum 22 and both springs are connected at 39 with the vertical bar 23. At the lower corners of the carriage Care hooks l0 with which either chain can be engaged when lifting a basket out of either tank by the turningof the crank, this being necessary when only one basket of dishes is suspended on the lever.

In practice, ,a basket of dishes isplaced in the tank 3 that has a washing fluid and allowed to remain therein during the packing of the second'basket, and when the latter is to be placed in the washing tank, the operator attaches the right-hand chain to the bail of the basket in the washing tank and with left hand on bottom cross bar of frame C to steady it, he turns the crank with the other hand so as to wind the cable 24 on the drum 27 until the springs are tense and the basket begins to rise. The crank is then released and the left hand grips the left chain -while the lower end of the right hand chain and bail of the basket are gripped with right hand and both arms are used for 'oscill'a'ting the lever to work the basket up and down in the washing tank. 'After the washing is completed the left-hand chain is fastened to the left-hand hook 40 so that the basket can be raised completely'out of the washing tank by the-turning of the'crank. The pawl will chain the carriage is moved to the right, and the left chain is engaged with the basket in the rinsing tank at the same time. The second basket is placed in the washing tank and engages hook on chain as it descends the balance lever already resting on the abut ment a1. After this is done, the crank is turned to raise the lever a suitable distance so that the baskets will be free from the stools or supports in the tank, and while the pawl holds the basket suspended the operator oscillates the lever to simultaneously work the baskets up. and down in the tanks. W hen the washing and rinsing operation is completed, the crank is again turned to raise the lever to its full height where the baskets will be above the sink. the baskets suspended thereon is moved to the left until the left and right baskets are over the drier B and left or rinsing tank respectively. The pawl is now re eased ar the crank reversed to permit the baskets to lower, one upon the discharge table over the drier, and the other into the rinsin tank. The chains are now released from the baskets and the carriage returns to initial position so that the second and third basket of dishes can be rinsed and washed in the same manner, while the rinsed dishes in the first has. kets arebeing dried by the heat from the drier B.

On the bottom of the carriage frame is anabutment 41, which limits the downward movement of the lever so that the lever can tilt su'flicicntly to permit the chains to be attached to or removed from the bails of the' The carriage with baskets When the-latter are resting on supv ports 15 in the tanks, and also gives room the other manipulates the crank. v

lVith an apparatus of this character, the washing can be carried on very rapidly and for the hand to rest on lower crossbar while i with great easeand furthermore,'there is economy in the use of water since the dishes are thoroughly washed in the yvashing tank and cleansed before being placed in the rimsing tank and it will be noted thatthe baskets of dishes are suspended in the upper part of l the tank so that the water is notag'itated sufficiently to stir the settlings in the bottom and; for this reason no food Will be earrie." with the dishes into the rinsing tank.v From the foregoing description taken in connection with the accompanying drawings, the advanta es'of the construction and of the method of operation will be readily a )parentto those skilled in the art to which t e invention relates, and while I. have de v cribed the principle of operation of the in vention, together with the device which I .now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be ma de when desired as are within the scope'of the invention What I claim as new and desire to secure by Letters Patent is:
